SICK 6044736, model WL280-2P2431 from the W280-2 series, is a compact photoelectric retro-reflective sensor designed for industrial object detection applications. Using visible red LED light with a polarisation filter, it detects objects by monitoring the reflected beam from a compatible reflector, making it suitable for conveyor lines, packaging machinery, handling systems and general automation equipment.
This sensor features a rectangular ABS housing with PMMA optics and measures 23.5 mm x 74.5 mm x 63 mm. It operates from a 10 V DC to 30 V DC supply and provides a PNP switching output with selectable light/dark switching via rotary selector. The sensing range is up to 13 m with PL80A reflector or up to 11 m with the supplied P250 reflector, with maximum ranges of 15 m and 12 m respectively depending on reflector type.
The WL280-2P2431 is built for reliable performance in demanding environments, with IP66/IP67 enclosure protection, a response time of ≤ 0.5 ms and a switching frequency of 1,000 Hz. Connection is via a 4-pin M12 male connector, and the unit includes built-in protection against reverse polarity, interference pulses, overcurrent and short circuits. The standard supply scope includes the BEF-W280 mounting bracket and P250 reflector, providing a practical sensing solution for industrial automation installations.

What type of sensor is this?
It is a compact photoelectric retro-reflective sensor from the W280-2 range, designed to detect objects by transmitting visible red LED light towards a reflector and monitoring the returned beam.
How does the retro-reflective sensing principle work?
The sensor emits a light beam towards a reflector. When an object interrupts the reflected beam, the sensor changes its switching output, allowing it to detect presence, position or movement in an automation system.
What sensing range does this sensor provide?
With a PL80A reflector, the sensing range is 0.01 m to 13 m, with a maximum range up to 15 m. With the supplied P250 reflector, the sensing range is 0.01 m to 11 m, with a maximum range up to 12 m.
What output type does the sensor use?
This model uses a PNP switching output with a maximum output current of 100 mA.
What supply voltage is required?
The sensor operates from a 10 V DC to 30 V DC supply, making it suitable for common industrial DC control circuits.
What connection type is fitted?
It is fitted with a 4-pin M12 male connector. The connection layout is pin 1 for L+, pin 3 for M, pin 4 for Q output, and pin 2 is not connected.
Can the switching behaviour be changed?
Yes. The sensor has selectable light/dark switching via a rotary selector, allowing the output logic to be adjusted to suit the application.
What is the response time and switching frequency?
The response time is 0.5 ms or less, and the switching frequency is 1,000 Hz, making it suitable for fast object detection tasks.
What environmental protection rating does the sensor have?
The housing is rated IP66 and IP67, giving protection against dust ingress and water exposure in demanding industrial environments.
What are the operating temperature limits?
The sensor is designed for operation from -25 °C to +55 °C. Its storage temperature range is -40 °C to +70 °C.
What materials are used in the housing and optics?
The housing is made from ABS plastic, while the optical components are made from PMMA plastic.
What is included with the sensor?
For Sick 6044736, the standard scope includes the BEF-W280 mounting bracket and a P250 reflector.
What accessories are commonly used with this sensor?
Common matching accessories include the P250 reflector, BEF-W280 mounting bracket, BEF-WN-REFX universal reflector bracket, M12 4-pin sensor cables and M12 field-wireable connectors.
What are the approximate dimensions?
The sensor body measures approximately 23.5 mm wide, 74.5 mm high and 63 mm deep.
What kind of light source does it use?
It uses a visible red LED light source. The light spot size is approximately 260 mm at a distance of 8 m.
